======================================================================
++ In rimefeller mod option, whatever I choose to do with the pipeline display option, that error log appears.
++ That error log appears when the pipeline is installed on the bed and workbench.

It's never been like this before, but I think it's because I installed a lot of modes recently. But there is no Rimfeller-related mode...
Plz help me.
